Magnoliales

Encyclopedia : M : MA : MAG : Magnoliales

Magnoliales is a botanical name for an order of flowering plants.

In the APG II system, of 2003, this order is placed in the clade magnoliids and is circumscribed as follows:

This is exactly the same as in the APG system, of 1998. In both these systems, published by the APG, the Magnoliales are a basal group, excluded from the eudicots.

The Cronquist system, of 1981, placed the order in the subclass Magnoliidae of class Magnoliopsida [=dicotyledons] and used this circumscription:

The Thorne system (1992) placed the order in superorder Magnolianae, of subclass Magnoliidae [= dicotyledons ], in the class Magnoliopsida [= angiosperms ] and used this circumscription (including the plants placed in order Laurales and Piperales by other systems): The Engler system, in its update of 1964, placed the order in subclassis Archychlamydeae in class Dicotyledoneae [=dicotyledons] and used this circumscription: The Wettstein system, latest version published in 1935, did not use this name although it had an order with a similar circumscription with the name Polycarpicae. This was placed in the Dialypetalae in subclass Choripetalae of class Dicotyledones.

From the above it will be clear that the plants included in this order by APG have always been seen as related. They have always been placed in the order Magnoliales (or a predecessor). The difference is that earlier sytems have also included other plants, which have been moved to neighbouring orders (in the magnoliids) by APG.
